HOP-JACK.

Specification of Letters Patent.

Patented July 16, 1907.

To all whom it 'm (1y contain..-

HEIMER, a citizen ol the United States, residing at Chicago, in thecount-yo! Cook and State 01' Illinois. have invented a new and usefulImprovement in 110p- Jocks of which the following is a completespceilicu tion.

This invention relates to improvements in hep jacks and moreparticularly to a hop jack provided with a 10 wort.

Heretofore hop jacks have usually been constructed with u perforatedfalse bottom, rais d distance above the bottom of the tank. and whichserves to separate the hops from the wort. This has been objectionablefor various reasons, among which are, first, thedilticulty in cleaningthe hops off the false bottom after the wort has been separated, second,it the wort is allowed to rise to a point too near to the false bottom,the suction of the pump in drawing of! the wort causes particles of thehops which entii ly cover the false bottom, to'loe drawn into the'ierforntions ol the bottom thus clogging the same, and third, where thefalse bottom is employed, and especially in the more recent com placedabove the cooler, it often happens that the wort rises above the falsebottom and stands in contact with thehops and, if allowed to stand forany length ottime, tlle hops impart to the wort u rank, hitter taste.

The Object of this invention is to provide a hop jack in which thescreen or strainer is so constructed that the wort quickly drains oh andthe hops are quickly and, thoroughly sparged and removed from thegreater portion of the surface of the screen by mechanical means,thereby obviating n great deal of the manual lahoi' usually requiredwhere a lalsc bottom is employed.

It is it further object of the invention to provide a device in whichthe danger of having the hops drawn into the separated wort is entirelyavoided, since there free passagc oi air provided l'rom the atmosphere.150 the tank without passing through the screen.

- t It is also an object of the invention to provide a hop jaelq inwhich the danger oi the wort. standing too long 1n ,cohtat with the hopsis entirely ol vialcd.

I The invention ermsists ol' the matters hcrcinullcr do scribed in thespecification and more lully pointed out and defined in the appendedclaims.

" In the drawings; Figure l is :1 top plan view or u do ice "embodyingmy invention. l i 2 taken on line ;r-:r of Fig. l. Fig. 3 is afragmentary end elevationol the power cud or the device, Fig. t is iifragmentary set ion taken on line y g; of Fig. l.

Al shown in aid druwings: i represents a any preferred siw. shape ml al-rial, proh-ral/l\ is a sect ion structions of breweries where the hopjack is: generally revolving screen adapted to scpiuute the hops fromthe 3 her not shown. Said tank is providcd with a daring bottom l at thelowest point ol which is an outlet pipe 1 its is usual in such devices.puriiul cover 1* is provided which covers all hut the central portion ofthe tank at. ourend and in which are the doors or lids l by means ofwhich access is had to the interior of the tank. Over the uncoveredportion ol the tank is mounted the screen casino 2 which has no bottomand opens directly into the tank. r\ \'t'lll pipe 2 leads lherclrom tothe ill iuosphcro and dpor I opt-n through the sides thereof and attordadmission to the screen.

At one end of said casing is pro\ idcd an enlar ine as shown moreclearly in Figs. L

ed openand l, about which is rigidly engaged, n the outer sidt oi thecus iiig, a circular lluue'c 1- into which the adjacent cud of thescreen i extends and which, as shown, is of grcnter diameter at ll outerend than at its inner end. A lid I3 is hinged on a piiitl(-3-o|1sui lflange and is adapted to he held in closed position h v means-oi an arm3-, which is pivoted on said piutlc and t-Xlclids outwardly anddownwardly to the opposite side of the lid. On the lowcr end of aid armis a catch ll" adapted to engage a suituhlc lug Ir" on the llau c'c andccntrnllv of said arm is a set scrcw 3;" adapted to cugagc the lid andl'orce it into close contact with the outer edge ol the Hang-c. .\l theoppositc cud of suid casing is provided on opening: ol smaller diameterthan thc opening in the front cud, hut in axial aliucmeut therewith, andsurrounding which, on the outer side ol the casing is the stuiliui; hexuid screen i may he oi uuy prcl'erred material, prcl'crahly copper, andas shown compriscs at conical shaped drum, the larger or front cud 01'which projccls into the tlnnge 3. lleucuth the so :eu and at each sideof the center lhcr ol is pivoted a hill 3 on stud shafts ll secured tothe casing. A t the ends oi said bars are journalcd rollers it" whichsupport the cud ol' the screen and afford a roller heariuc therefor. Therear or smaller end of said screen is provided with a head i, which isrigidly engaged therein, and is provided with an outwin'dly directedcylinder allot-ding an axle 4- in axial ulinement with the screen, andwhich extends outwardly through the stulling box 2 Sold cylinderprovided zit s outer l'lltl with a-pcriph rul [hinge which is seated ina. colnplenn-nlal greove'in the hearing scat ol: the hearing standard 5,,carried onlhocover l, and prevents longitudinal movement, of the screenwhile pcrtuittiiu, it. to rotate freely. Said .scrceu nnty be operatedivy any desired power but as shown an electric motor t; is mounted onthe tank and the motor shall 15" i.

tt nivt the a. A ra-huivcly largo worm d on the axle -l'-' and is inmosh n on rho \\Ul'l l shalt nud transmits lllt. ino- Limil therein tothe o.

w th the n c it on Fitting. closely in the end of the axle 4 and extend;

ing outwardly therefrom is a pipe section 8 which is connected at itsouter end in the pipe fitting 9 into one side 7 of which opens thesupply pipe 10 leading from the ketile, not shown. J ournaled in saidfitting and opening thereinto, in axial alineinent with the pipe 8, isthe hollow shaft 11, the outer end of which is journaled in the bearingstandard 12 carried on the t p of the tank.

For the purpose of thoroughly removing the wort An arm 14 is rigidlyengaged on said shaft adjacent said bar and engaged in the end thereofis the perforated pipe 14, the other end of which is turned inwardly andengaged in said pipe f tting 1. Rigidly engager on said pipe 14 andextending into close proximity with the screen is the'scraper 15 adaptedto scrape the hops from the walls of the screen. A hot water pipe 16leads from any suitable sourcebf supply and is connected in the outerend of the shaft 11, by means affording a tight joint and is adapted tosupply hot Water to the sparger. For the purpose of rotating saidsparger or sprinkler and the scraper, a gear 17, in mesh with the wormgear '7 as shown dotted lines in Fig. 3, is rigidly engaged on ashaitlB, journaled in suitable standards 19 which are engaged on the topof the tank. A gear 20 is loosely engaged on the shaft 18 and mesheswith a gear 21 which is rigidly engaged on the tubular shaft 11. Aclutch 22 of any preferred construction acts to lock the gear 20 to theshaft 18 when it is desired to rotate the sparger. The

gear 17 is much smaller than the gear 7 as are the gears 20 and 21 andtherefore the sparger and scraper are caused to revolve faster than thescreen. fits closely in the large end of the drum against the bar 13 andmay be secured therein in any preferred manner, not shown.

The operation is as follows: The wort with the contained hops isadmitted through the pipe 10 to the screen where the wort escapesthrough the perforations into the tank, leaving the hops. As soon as thewort is turned into the screen the latter is started re\-olving therebydistributing the hops over its sur-- face and causing the greaterportion of the wort .to strain into the tank, and only that remainingwhich has been absorbed by the hops. The sparger-and scraper are thenset in motion-by means of the clutch 22 and the hops arerepeatedlyscraped from the walls of the screen and turned over. At the same timehot water is admitted through the pipe 16 and thoroughly sparges thehops thereby removing all the remaining wort; Owing to the conical shapeof the screen the hops gradually'work towards the larger or front endand when the Work has been completely separated the lid 3 and door 23are removed and the hops withdrawn from the screen.
